Clean Your Coils, Ducts & Filters

Cleaner systems use less energy and just work better.

A little light cleaning goes a long way to keep your systems running smoothly and efficiently. Clean radiator or duct vents, routinely replace your HVAC filters, rinse your outdoor central air conditioner coils once a year, and keep your refrigerator coils clean and free of dust. Clean HVAC filters also reduce the allergens and other particles in your air, which helps to keep your home healthy. Check your filter once a month during high-use winter and summer seasons.

Do I need any special equipment to for cleaning vents and refrigerator coils?

Your vacuum attachments should be all you need to suck up the dust bunnies from under and behind your refrigerator. It’s helpful to start with a long handled brush to remove any dust that has collected on the evaporator coils. The duster attachment should also work well to clean your heating/air conditioning duct vents.

How do I know what type of filter is best for my furnace?

Your best bet is to check your owner’s manual. If that has been misplaced, take a look at the filter already in the system. The filter type and size should be legible on the cardboard sides of the filter. There will also be arrows printed on the sides; it’s important to make sure the filter is inserted properly to match the direction of air flow.

If the filter does not have a cardboard frame it is probably a reusable filter. In this case just soak the filter briefly in warm soapy water. A drop of mild dish detergent will do. Shake the filter and make sure it is dry before putting it back in your furnace.
